Scott mentioned dial backlash. There must have been a problem with his radio! Its a direct drive and I can't imagine how you could get backlash unless the 'disc' had worn spots. It's been a long time and I don't remember if I felt backlash on my Hammarlund but I do remember I didn't like the tuning. I think they used a cheap (for the day) gang cap and it was probably too light. Direct drive or not, a crappy tuning cap is going to give you bad feel and crappy tuning. If you really want a Hammarlund at least see if you can try it out in person or get a trial period. There are certainly better radios around. My HQ-145XC has been re-capped and new tubes, and is smooth and a very good AMBCB DX machine. I rarely listen to SW anymore, not much to hear like when I was in HS in the 60s. I have always loved the look and the quality of Hammarlund radios. I had to start off with a crappy Hallicrafter's S-120 from Sears. I always wanted an HQ-180, still do! What other radios do you think are better? |

I used an HQ-170 for several years (a long time ago!) The vernier tuning
(plus/minus 3 kcs, IIRC) was wonderful. Otherwise, based on later receivers, it was not that impressive. The internal "hiss" level was higher than many other receivers. (I worked 99% CW.) It had USB/LSB selectivity, but it was not great. There should be no backlash. Some functions, like the noise slot, were not very useful. Only later versions had 6 meter coverage; mine did not. The clock was nice, but it was just a clock. HQ-170s are relatively cheap on ebay. (I bought one a few years ago, just for old-time memories, and sold it shortly thereafter. It does not measure up to more modern receivers.) HQ-180s (in reasonable condition) are not cheap. For general shortwave listening, they are considered a high-end unit but this is a different category than serious ham usage (especially for chasing weak DX with minimal antennas, which was my HQ-170 experience). As several people have mentioned, short-wave broadcasting is not was it was a few decades ago and is generally disappearing rapidly. You can still find the religious stations, if that is of interest. I think your decision should depend on what you want to do with it. A good HQ-145X should be ample for general short wave listening, unless you have a very specific and difficult interest. An HQ-170 is ham-band only (without WARC and maybe without 6 meters). An HQ-180 may be better for more intense shortwave listening if you have specific objectives in mind. A good HQ-180 is likely to be much more expensive than the other two. Bill - W2WO |

Audio was warm like Bill Haley and the Comets on Fender tube (of course!) amps, and that heavy heavy tuning flywheel could almost spin across the whole band with one flick of the wrist. I believe it had 6 bandwidths from about 6K down to 250Hz. I haven't seen a better tube CW rig ever. SWL was great on it too. They seem to be loved by everyone who had one or ever used one. They were huge though, make room in the shack. |

What modes does he really want to listen to, e.g., teletype, digital, cw, ssb, am, fm? What frequency range is desirable? Would he want VHF and UHF if he could get it? How about frequency setability? How about a computer interface to the receiver? Does it have to have knobs, or is a Software Defined Receiver ok? Is sensitiity more important than selectivity? Must it look "pretty"? Better is also a function of $. What kind of $ range is to be considered. Ed, N5EI |

Better is also a function of $. What kind of $ range is to be considered. And I suspect at this point that "better" may not be the only criteria. The H1-180 was about a decade old when I first read about it, coming into the hobby in 1972. It always seemed intriguing, something different about it, even though it wasn't the only receiver at the time it came out that dropped to 60KHz for selectivity with LC circuits (and thus supplying multiple bandwidths with less limitation of the phasing type crystal filter). So wanting it now might be because of that lust when it came out and was too expensive. There were lots of receivers that came out that had some neat thing about them, or others that were barely discussed, and yet they may take precedence over the "better receivers" because it's the unique that's desired, not "best reception". Now, so many have transceivers (or a matched pair of receiver and transmitter), and if recent enough, they even have general coverage reception built in. So like I said, criteria is different now from even forty years ago, when you'd be trying to stretch a general coverage receiver to ham use. If you now have the function of general coverage, and generally good design, then the novelty of that Clegg receiver with the external converter so it covers the shortwave bands is much more appealing, whether or not there are "better receivers". I'm not just talking about collecting, but that one can still lust after an old receiver without it being Top of the Line (though perhaps one lusts after those at the same time). Michael VE2BVW |

![]() Hi, I've got an HQ-170C. I'm surprised no one mentioned drift. It's fine for cw/am, but SSB is a trial, unless you let it run 24/7. The HQ-170C is the same as the HQ-170, except it includes the optional clock. My receiver required a realignment to get back the very sharp selectivity designed into it. The audio system has a strange design, where the level you set the gain control also affects the audio bandwidth. If the audio is cranked up high, for weak signal reception, audio bandwidth will be reduced. It never bothered me, but it is something to be aware of. The HQ-170AC added a separate, always-on filament transformer for the HF oscillator and first mixer tubes, which must have helped stability greatly. The HQ-170AC also solid-stated the power supply, removing the 5U4 rectifier, a big source of heat. The HQ-170A/VHF (last of the '170 line) added a built-in 2 meter converter designed by Frank C. Jones. 73, Ed Knobloch |

The HQ-170C is the same as the HQ-170, except it includes the optional clock. That's true, because while it's multiple conversion, the crystal oscillator is the second conversion (unlike the Collins sort of design, where it's a tuneable receiver with a crystal controlled converter ahead of it), so the receiver has the local oscillator is an LC oscillator running almost up to 30MHz or, the only difference from the average single conversion receiver of the era is that when it goes to triple conversion the LO is offset by 3MHz. Considering that stability was always an issue when the LO went up towards 30MHz with no synthesizer, the receiver can't be that different from the average receiver (except to the extent Hammarlund put into stabilizing the oscillator). As someone once pointed out, the Collins type arrangement wasn't just to get rid of image rejection, it allowed for a linear scale that was good for each band, and kept the LC LO at a reasonably low freqnency. My receiver required a realignment to get back the very sharp selectivity designed into it. The audio system has a strange design, where the level you set the gain control also affects the audio bandwidth. If the audio is cranked up high, for weak signal reception, audio bandwidth will be reduced. It never bothered me, but it is something to be aware of. Is that the "variable response audio system" mentioned in the "73" listing? I read the listing as meaning "tone control". The HQ-170A/VHF (last of the '170 line) added a built-in 2 meter converter designed by Frank C. Jones. I was going through more magazines last night, and noticed an ad for that one. It didn't mention Frank Jones, which seems odd since it does seem a selling point, his VHF book, all those converter articles (a new device would appear, like a nuvistor, the transistor, the FET) and he'd issue a set of articles, new converters for each of the 50 to 420MHz bands using the new device. When Tapetone, or was it Redline, came out with a new converter, they featured Sam Harris as a "proud owner". Michael VE2BVW |
